Abstract
A probe tip is employed to measure electromagnetic fields without the use of a metallic conducting wire or cable which would otherwise distort the field being measured. The probe tip includes a variety of different circuits, each of which contains a separate battery, a powered field measurement sensor and an amplifier. A light source, which is internal to the probe tip and coupled to the amplifier, operates to convert the measured field to an analog optical signal. The analog optical signal is transmitted via an optical fiber to a receiver/preamplifier circuit which converts the optical signal to an electrical signal at the fiber's far end. This receiver/preamplifier device can be coupled directly to an oscilloscope or other instrument which are employed and used for the display or recording the magnitude of the electromagnetic field as measured by the probe.
